[WP] Creating RoyalSlider for NextGEN gallery

Limitations:

  • Slider supports: NextGEN galleries, groups of images (like random images), but doesn't support different kinds of albums.
  • Default RoyalSlider caching doesn't work with NextGEN type due to specifics of NextGEN gallery, so it's recommended to use caching plugins, like W3 Total Cache for high-load websites.
